Title:
ANTENNA DEVICE AND ANTENNA DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/100908
Kind Code:
A1
Abstract:
[Problem] To avoid an enlargement in a direction orthogonal to the radiation plane due to a transmission line for electric power, and facilitating obtaining a desired antenna gain. [Solution] This antenna 50 has a radiation plate 56 provided with a radiation plane that radiates a radio wave and a feeding point 56A that is a section supplied with electric power from a transmission line 70A. When the radiation plate is viewed in the horizontal direction, the feeding point is provided at a position separated from the center of gravity 56B of the radiation plate by a distance A. When the radiation plate is viewed in the thickness direction, a section of the transmission line between the end portion connected to the feeding point and an intersecting portion 70A4 that intersects an edge portion of a conductor plate overlaps a specific area SA between a third straight line L3 and a fourth straight line L4 in the thickness direction of the radiation plate.
